Anti repeat table?

[ella]

ok, so lets say I made a trigger that says hi to everyone using their name when they arrive. is there some way I can store that name on a table AND keep it from firing off again?

You could use something like the following.(not tested)

Code: [show] | [select all] lua

greeter = greeter or {}
greeter.people = greeter.people or {}

function greeter.sayHi(person)
  if greeter.people[person] then
    return true
  end
  greeter.people[person] = true
  send("say to " .. person .. " hello!")
end

Call it in your trigger with, e.g. "^(\w+) entered the room\.$" with

Code: [show] | [select all] lua

greeter.sayHi(matches[2])

This will work per session; meaning when you close the game window, the persons list will clear.

If you want to clear the list every time you log off, call

Code: [show] | [select all] lua

greeter.people = {}

upon logout.
